systemd-remount-fs.service, systemd-remount-fs \- Remount root and kernel file systems
.SH "SYNOPSIS"
.PP
systemd\-remount\-fs\&.service

.SH "DESCRIPTION"
.PP
systemd\-remount\-fs\&.service
is an early boot service that applies mount options listed in
\fBfstab\fR(5), or gathered from the partition table (when
\fBsystemd-gpt-auto-generator\fR(8)
is active) to the root file system, the
/usr/
file system, and the kernel API file systems\&. This is required so that the mount options of these file systems \(em which are pre\-mounted by the kernel, the initrd, container environments or system manager code \(em are updated to those configured in
/etc/fstab
and the other sources\&. This service ignores normal file systems and only changes the root file system (i\&.e\&.
/),
/usr/, and the virtual kernel API file systems such as
/proc/,
/sys/
or
/dev/\&. This service executes no operation if no configuration is found (/etc/fstab
does not exist or lists no entries for the mentioned file systems, or the partition table does not contain relevant entries)\&.

Note:
systemd\-remount\-fs\&.service
is usually pulled in by
\fBsystemd-fstab-generator\fR(8), hence it is also affected by the kernel command line option
\fIfstab=\fR, which may be used to disable the generator\&. It may also pulled in by
\fBsystemd-gpt-auto-generator\fR(8), which is affected by
\fIsystemd\&.gpt_auto\fR
and other options\&.
